Neat game, found a few bugs though:
- The map (at least I'm assuming that's what it is) opens off-screen for me, possibly because of the 1440p resolution? Here's a screenshot: 
- You can open the map while dying
And some general suggestions:
- When jumping up ladders is the fastest way to climb them then that's the only way people are going to do it, so maybe put a cooldown on it or something
- it would probably be nice to be able to attack while on a ladder
